When asked by the club's official website whether Arsenal were a club on the rise, he replied: "Yeah definitely. They've done well in recent years and last year we got the FA Cup and I feel like it's time where we could really push on and try and challenge for the Premier League title. I've got one medal and it's something that I really want to add to.

"I believe the style of play the manager's got and the boys play and with the magnificent players in midfield slotting balls through, I can run on to the end of those balls and slot them away.

"I'd like to bring pace and power to the game. At Arsenal, we're not short of combination football and I like to join in on that and get in behind defenders and try to get shots off at goal. I want to score some goals and help the team to achieve the right results."

Welbeck scored 29 goals in 142 appearances for United before joining Arsenal.

The United youth academy graduate expressed his delight at finally signing for the Gunners after the drama of trying to finalise his deadline-day move from Old Trafford to the Emirates Stadium.

"It's exciting times for me," he said. "It's great to be a part of this club and it's a team that I've always watched in the Premier League. I've envisaged myself playing in this team before. For it to finally happen is very exciting.

"[The move] went right down to the wire in the end. It's difficult to say how I felt at the [different] times of each day because the deal was on and then it was off but at the end of the day I'm an Arsenal player and I couldn't be any happier at the moment."

Welbeck was born and raised in Manchester just a few miles from Old Trafford, but despite his affection for his boyhood club, the striker insists he is ready to move on and prove himself for Arsenal.

"I've been at United ever since I was a little boy and I had a great time there," he said. "I just think this is the next stage of my development -- to come to Arsenal, to really show people what I can do as a footballer and hopefully get to the place where I want to be.

"Things move on in life and I think you've really got to make the right decision in the situation that you're in at that moment in time. I really do believe that coming to Arsenal is the right decision."
